Answer:
The answer is D(20)
Step-by-step explanation:
I don't know the exact algebraic explanation, however, this is how I did it.
If you divide the second equation into seperate twos, you will get 2*2*2*2*2*2 =
Therefore, meaning that x is equal to 6. Now The next bit is trial and error, 20-6=14.
Last thing to do is to add x+y=6+14. That is why the answer is 20.
If you wait a bit longer, someone will probably have a more algebraic explanation, however, you stated you only needed the answer so I hope this helped.

Change 1 hour 15 minutes = 1.25 hour because 15 ÷ 60 = 0.25 so we add 0.25 hour and change 2 3/4 to 2.75
Equation:
Multiply 2.75 × 1 = 2.75 ÷ 1.25 = 2.2 miles
I'm pretty sure this is correct
Equation:
Multiply 2.75 × 1 = 2.75 ÷ 1.25 = 2.2 miles

Answer:
a = 2, b = 3.5
Step-by-step explanation:
Expanding using Binomial expansion, we have that:
=
We have that the coefficients of the first two terms are 128 and -224.
For the first term:
=>
=>
For the second term:
Therefore, a = 2, b = 3.5
